Scientists like Stephen Hawking had long tried to solve the mysteries behind black holes, but until now, no expert has successfully cracked the reality behind these dark entities in the universe. However, a black hole collision which happened nine million light years away from the earth could shed light on the nature of this

"This event also had black holes spinning the fastest of all mergers observed so far. It is also by far the most distant merger observed,"

Space is literally all around us, but it’s notoriously difficult to wrap our minds around it. Given the hundreds of billions of stars and planets that make up our galaxy alone, who can be blamed for a lack of cosmic perspective, even if NASA’s InSight explorer just landed on Mars to send some back? As an astronomer at the Adler Planetarium in Chicago, I spend a lot of time...

Sydney: A team of scientists have detected the gravitational waves that resulted from the biggest collision of black holes ever observed and which formed a new black hole about 80 times larger than the sun. This and three other black hole fusions were detected by an international team of scientists formed by the Advanced Laser Interferometer Gravitational-Wave Observatory...

So far the US-based LIGO and Europe-based VIRGO gravitational-wave detectors have recorded gravitational waves from a total of 10 black hole mergers and one merger of neutron stars. The new events are known as GW170729, GW170809, GW170818, and GW170823, in reference to the dates they were detected. GW170729, detected in the second observing run on July 29, 2017, is the most...

An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun - and from another three black-hole mergers.

A mammoth asteroid, measuring more than one mile in diameter will have its closest approach with earth on the wee hours of December 22, 2018, NASA has warned. At its closest approach, the space rock dubbed 'Asteroid 2003 SD220' will skim past earth within 0.01890 astronomical units (AU) or 1.7 million miles. It should be noted that one astronomical unit is equal to about 92.95...

A gigantic rogue asteroid named '2018 VE4' will zip past earth today, NASA has warned.

As per experts, the rogue space body is approximately 160 feet long, and it is apparently travelling across space at a...

Largest ever black hole collision detected by scientists
Two black holes are thought to have formed a new black hole 80 times larger than the Sun and sent ripples through space-time.
An international team of scientists have detected the largest ever black hole collision through the ripples it made in space-time.
US scientists discovered the space-time ripples - officially known as gravitational waves - in a breakthrough in 2016, although their existence was predicted by Albert Einstein roughly a century ago.
Now academics at the Australian National University (ANU) have detected the collision between two black holes, which are believed to have formed a new black hole about 80 times larger than the Sun.
The ANU team worked in partnership with other academic institutions through the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO), which is based in the US.
ANU Professor Susan Scott said the team discovered four collisions in total by re-analysing data captured during Advanced LIGO\'s first two observing runs.
Among these was the formation of the biggest known black hole, created in the collision and merger of a binary system of black holes on 29 July 2017 - about nine billion light years away from Earth.
Professor Scott said: \"This event also had black holes spinning the fastest of all mergers observed so far. It is also by far the most distant merger observed.\"
The team published computer calculations modelling the gravitational waves it observed and the black holes that emitted waves.

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein\'s general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light.
Just about every galaxy the size of our own Milky Way or larger contains a monster black hole at its center. Observations show galaxy mergers occur frequently in the universe, but so far no one has seen a merger of these giant black holes.
Scientists have detected merging stellar-mass black holes -- which range from around three to several dozen solar masses -- using the National Science Foundation\'s Laser Interferometer Gravitational-Wave Observatory (LIGO). Gravitational waves are space-time ripples traveling at the speed of light. They are created when massive orbiting objects like black holes and neutron stars spiral together and merge.
Supermassive mergers will be much more difficult to find than their stellar-mass cousins. One reason ground-based observatories can\'t detect gravitational waves from these events is because Earth itself is too noisy, shaking from seismic vibrations and gravitational changes from atmospheric disturbances. The detectors must be in space, like the Laser Interferometer Space Antenna (LISA) led by ESA (the European Space Agency) and planned for launch in the 2030s.

Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy. And, with the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. Join Brian Greene and other leading physicists and astronomers on a journey to make darkness visible.

This computer simulation shows the warping of space and time around two colliding black holes observed by LIGO on September 14, 2015. LIGO detected gravitational waves generated by this black hole merger—humanity\'s first contact with gravitational waves and black-hole collisions. Gravitational waves are ripples in the shape of space and flow of time.
The colored surface is the space of our universe, as viewed from a hypothetical, flat, higher-dimensional universe, in which our own universe is embedded. Our universe looks like a warped two-dimensional sheet because one of its three space dimensions has been removed. Around each black hole, space bends downward in a funnel shape, a warping produced by the black hole\'s huge mass.
Near the black holes, the colors depict the rate at which time flows. In the green regions outside the holes, time flows at its normal rate. In the yellow regions, it is slowed by 20 or 30 percent. In the red regions, time is hugely slowed. Far from the holes, the blue and purple bands depict outgoing gravitational waves, produced by the black holes\' orbital movement and collision.
Our universe\'s space, as seen from the hypothetical higher-dimensional universe, is dragged into motion by the orbital movement of the black holes, and by their gravity and by their spins. This motion of space is depicted by silver arrows, and it causes the plane of the orbit to precess gradually, as seen in the video.
The upper left numbers show time, as measured by a hypothetical person near the black holes (but not so near that time is warped). The bottom portion of ...

Two colliding black holes send ripples through the space-time fabric of the Universe that are called gravitational waves. It is possible for two black holes to collide. Once they come so close that they cannot escape each other\'s gravity, they will merge to become one bigger black hole.

When black holes collide, the energy of the event generates intense gravitational waves. These waves were predicted by Einstein in his theories, but scientists have only recently been able to detect them experimentally. In this SciCafe, Barnard College professor and astronomer Janna Levin shares her
